Description

UC2843AD8 Overview
In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. 1 outputs can be generated with the dc motor controller. The pmic is packaged in Tube solid enclosure. With this function, you can deal with Transistor Driver dc switching's outputs (s). DC control operates at 7.6V~30V volts and has 7.6V~30V supply voltage. A -40°C~85°C TA dc switcher is not a problem. Switching can be done at Up to 500kHz with this switching controller. The Surface Mount makes it ideal for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Frequency Control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. 8 terminations with various dc switching's functions. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. UC2843 can be searched for other relevant dc to dc converter ics. Total pins of switching converter are 8. Switching converter is a type of Switching Regulator or Controllers in particular. As determined by the test statistics, the output voltage of DC regulator is 15V. In most cases, the dc dc regulator's output current is 1A. This information should be noted when you begin working with the component. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 100 % during power-up and power-down. A frequency of 250kHz is set for the switching controller. 25V is the nominal working voltage. The supply voltage should be 11V. In order to ensure proper operation, the controller should not receive more current than 25mA.

The UC3823A and UC3823B and the UC3825A andUC3825B family of PWM controllers are improved versions of the standard UC3823 and UC3825 family. Performance enhancements have been made to several of the circuit blocks. Error amplifier gain bandwidth productis 12 MHz, while input offset voltage is 2 mV. Current limit threshold is assured to a tolerance of 5%. Oscillator discharge current is specified at 10 mA for accurate dead time control. Frequency accuracy is improved to 6%. Startup supply current, typically 100 t,A, is ideal for off-line applications. The output drivers are redesigned to actively sink current during UVLO at no expense to the startup current specification. In addition each output is capable of2-A peak currents during transitions.
